    The pipes of energy plants and ocean structures are subject to local wall thinning, resulting from severe erosion-corrosion damage. Therefore, evaluation of failure pressure and fracture behavior of pipes must be necessary for getting integrity of them. This study investigated the failure behavior of carbon steel pipes with varying degrees of localized wall thinning under internal pressure conditions. The parameters included wall thinning shape, length, and depth. Failure mode was influenced by internal pressure, wall thinning length, and depth. A thickness ratio of 0.2 or more could safely withstand the internal pressure. Acoustic emission (AE) signals were detected when plastic deformation began. The dominant frequencies were found in the ranges of 78~195 kHz and 292~351 kHz.
